TRICARE Pharmacy Program: Costs, Tiers & Coverage (2026)
The TRICARE Pharmacy Program provides worldwide prescription drug coverage to more than 9 million beneficiaries. You can choose to fill prescriptions through military pharmacies for free, via home delivery (Express Scripts), or at thousands of retail network pharmacies. While the benefit is standardized, your specific out-of-pocket costs depend on the type of drug and your sponsor's military status.

In detail
The TRICARE Pharmacy Program is managed by **Express Scripts**. Unlike your medical coverage, which varies significantly between Prime and Select, the pharmacy benefit is largely the same across most TRICARE plans (Prime, Select, Reserve Select, and Retired Reserve).
### Fill Options and 2026 Costs Your costs are determined by the "tier" of the drug: Generic (Tier 1), Brand-Name (Tier 2), and Non-Formulary (Tier 3).
| Filling Method | Tier 1 (Generic) | Tier 2 (Brand) | Tier 3 (Non-Formulary) | | :--- | :--- | :--- | :--- | | **Military Pharmacy** (90-day supply) | $0 | $0 | Not always available | | **Home Delivery** (90-day supply) | $13 | $38 | $76 | | **Retail Network** (30-day supply) | $16 | $43 | $76 | | **Non-Network Retail** | Full cost upfront | Full cost upfront | Full cost upfront |
*Note: 2026 rates. Active duty service members (ADSMs) always pay $0 for covered prescriptions.*
### The TRICARE Formulary The Department of Defense (DoD) maintains a **Uniform Formulary**, which lists which drugs are covered. You can use the [TRICARE Formulary Search Tool](https://www.express-scripts.com/tform) to check: * If your drug is covered. * The cost (tier) of the drug. * If it requires **Prior Authorization (PA)** or **Medical Necessity (MN)** documentation. * If it is a "Maintenance Medication" required to be filled via mail-order.
### Maintenance Medications for Retirees Under the T-5 contract rules, retirees and their families must fill "maintenance medications" (long-term drugs for conditions like high blood pressure or cholesterol) via **TRICARE Home Delivery** or at a **Military Pharmacy**. If you continue to use a retail pharmacy for these specific drugs after two fills, you may be responsible for 100% of the cost.
### Regions and Management Regardless of whether you are in the **East Region (Humana Military)** or the **West Region (TriWest Healthcare Alliance)**, your pharmacy benefit is handled centrally through Express Scripts. Your medical contractor does not process pharmacy claims.
## Who this applies to * **Active Duty Service Members (ADSMs):** Always have $0 copays for any covered drug. * **Active Duty Family Members (ADFMs):** Pay the standard copays listed above; no deductible for drugs. * **Retirees and their Families:** Pay standard copays; may be subject to different "catastrophic caps" that limit annual out-of-pocket spending. * **TRICARE For Life (TFL) Beneficiaries:** TRICARE acts as the primary payer for pharmacy benefits even though Medicare is primary for medical. TFL users must follow the same formulary and mail-order rules. * **Guard/Reserve:** Members on TRS or TRR plans use the same tiered pricing structure.
Common scenarios
**Scenario 1: The Maintenance Medication** John is a retired Navy veteran living in Florida. He takes a daily Brand-Name statin for cholesterol (Tier 2). If he fills this at a CVS (Retail Network) for 30 days, he pays **$43**. If he switches to Express Scripts Home Delivery, he pays **$38** for a 90-day supply—saving $91 every three months.
**Scenario 2: The Emergency Antibiotic** Sarah is an active duty spouse on TRICARE Select. Her daughter gets strep throat and needs a generic antibiotic immediately. She goes to a network pharmacy like Walgreens. For a 30-day supply of this Tier 1 Generic, she pays **$16 (2026 rates)**.
**Scenario 3: Non-Network Costs** Mark uses a small "boutique" pharmacy that is not in the Express Scripts network. He fills a Brand-Name script for $200. He must pay the full $200 upfront and file a claim for reimbursement. TRICARE may only pay back a portion of the cost after he meets his annual deductible.
